Rule 8.02(b): "Have on his person, or in his possession, any foreign substance"

Here's Rule 8.02 from rule from the Official Baseball Rules. All rules under section 8.00 are about the pitcher. In the case of foreign substances, the part that seems to apply to the Pineda situation is 8.02(b), which makes it clear that a pitcher has to only be in possession of a substance to have violated the rule.

8.02 The pitcher shall not--

(a)

(1) While in the 18-foot circle surrounding the pitcher’s plate, touch the ball after touching his mouth or lips, or touch his mouth or lips while he is in contact with the pitcher’s plate. The pitcher must clearly wipe the fingers of his pitching hand dry before touching the ball or the pitcher’s plate. EXCEPTION: Provided it is agreed to by both managers, the umpire prior to the start of a game played in cold weather, may permit the pitcher to blow on his hand.

PENALTY: For violation of this part of this rule the umpires shall immediately remove the ball from play and issue a warning to the pitcher. Any subsequent violation shall be called a ball. However, if the pitch is made and a batter reaches first base on a hit, an error, a hit batsman or otherwise, and no other runner is put out before advancing at least one base, the play shall proceed without reference to the violation. Repeat offenders shall be subject to a fine by the League President.

(2) expectorate on the ball, either hand or his glove;

(3) rub the ball on his glove, person or clothing;

(4) apply a foreign substance of any kind to the ball;

(5) deface the ball in any manner; or

(6) deliver a ball altered in a manner prescribed by Rule 8.02(a)(2) through (5) or what is called the “shine” ball, “spit” ball, “mud” ball or “emery” ball. The pitcher is allowed to rub the ball between his bare hands.

PENALTY: For violation of any part of Rules 8.02 (a)(2) through (6):

(a) The pitcher shall be ejected immediately from the game and shall be suspended automatically. In National Association Leagues, the automatic suspension shall be for 10 games.

(b) If a play follows the violation called by the umpire, the manager of the team at bat may advise the umpire-in-chief that he elects to accept the play. Such election shall be made immediately at the end of the play. However, if the batter reaches first base on a hit, an error, a base on balls, a hit batsman, or otherwise, and no other runner is put out before advancing at least one base, the play shall proceed without reference to the violation.

(c) Even though the team at bat elects to take the play, the violation shall be recognized and the penalties in subsection (a) will still be in effect.

(d) If the manager of the team at bat does not elect to accept the play, the umpire-in-chief shall call an automatic ball and, if there are any runners on base, a balk.

(e) The umpire shall be sole judge on whether any portion of this rule has been violated.

Rules 8.02(a)(2) through 8.02(a)(6) Comment: If a pitcher violates either Rule 8.02(a)(2) or Rule 8.02(a)(3) and, in the judgment of the umpire, the pitcher did not intend, by his act, to alter the characteristics of a pitched ball, then the umpire may, in his discretion, warn the pitcher in lieu of applying the penalty set forth for violations of Rules 8.02(a)(2) through 8.02(a)(6). If the pitcher persists in violating either of those Rules, however, the umpire should then apply the penalty.

Rule 8.02(a) Comment: If at any time the ball hits the rosin bag it is in play. In the case of rain or wet field, the umpire may instruct the pitcher to carry the rosin bag in his hip pocket. A pitcher may use the rosin bag for the purpose of applying rosin to his bare hand or hands. Neither the pitcher nor any other player shall dust the ball with the rosin bag; neither shall the pitcher nor any other player be permitted to apply rosin from the bag to his glove or dust any part of his uniform with the rosin bag.

(b) Have on his person, or in his possession, any foreign substance. For such infraction of this section (b) the penalty shall be immediate ejection from the game. In addition, the pitcher shall be suspended automatically. In National Association Leagues, the automatic suspension shall be for 10 games.
